Subject: rtc: omap: fix error path when pinctrl_register fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=26e480f7bb7840fc0daa9c3af7c4501b2cf5902f;p=openwrt%2Fstaging%2Fblogic.git

rtc: omap: fix error path when pinctrl_register fails

If pinctrl_register() fails probe will return with an error without locking
the RTC and disabling pm_runtime.
Set ret and jump to err instead.

Fixes: 97ea1906b3c2 ("rtc: omap: Support ext_wakeup configuration")
